In some ways the potential of SMS as an interactive advertising tool is still not fully exploited. The Dutch service SMSeenhuis should be an inspiring example.
"SMSeenHuis ("Text a House") is a Dutch service that allows mobile users to text the Real Estate boards outside residential houses. In response, they get details of asking price, address, number of rooms and square footage, along with the Real Estate Agent contact details. Participating real estate agents pay a EUR 20 fee (USD 27 / GBP 15.50) subscription fee, EUR 50 per unique property code, and EUR 0.50 per text message (capped at EUR 50 per month)."
